The Treaty of Apamea was a peace treaty conducted in 188 BC between the Roman Republic and Antiochus III, ruler of the Seleucid Empire. It ended the Roman–Seleucid War. The treaty took place after Roman victories at the Battle of Thermopylae (in 191 BC), the Battle of Magnesia (in 190 BC), and after Roman and Rhodian naval victories over the Seleucid navy.
